Before this patch curl code was redefining `getaddrinfo` and `freeaddrinfo` system symbols to plug in its debug wrappers. This was causing pains to avoid applying the redefinitions to system headers defining these functions, and to the local debug wrappers. Especially in unity builds. It also required workarounds for systems where these symbols are already macros. Introduce curl-namespaced macros for these functions and use them. This allows to drop all workarounds and makes it work in all envs, local targets and unity/bundle combinations. Also drop GHA/windows workaround and use the same unity batch across all jobs.
